How Does a Hydraulic Motor Function in a System?

[Trainee]

Hey Respected seniors,
I want to know that how the hydraulic motor works?
Im working as a trainee engineer in a company..
I watch daily a machine that have hydraulic motor, pump, solenoid valve...
All these things are for the movement of a shaft which is connected to a jack( I see, there are two cables/nozzles for pump pressures attached with that jack..). ..

PLZ simply tell me how the hydraulic motor, pump, solenoid valve work together?

thanx & best regards

Hydraulic motors are basically water wheels. A fluid under pressure pushes against vanes attached to a shaft and makes the shaft turn. After doing a little pushing the fluid is drained from the motor and returned to the pump that pressurized it. The pump itself is just a reversed version of the motor -- something turns a shaft that has vanes which pushes fluid out of a port under pressure.

There should be some good diagrams of these things on wiki or google someplace if you poke around a bit.

Beating the analogy a little further, this is pretty much how an electric motor or generator works as well...see the Hydraulic Analogy.

thanx alot...

Actually the machine that I discussed is a SPREADER which is used with CRANES(ship to shore,sts, and rubber tyre gentry,RTG)..
So If anybody is working at PORT then I request him, please tell me in detail,thanx

The specific application is pretty much irrelevant, except perhaps as regards scale. The pump (vane or lobe type), under the influence of a drive motor, supplies pressurized oil to the motor (which is just a pump fed from the other end). The valve, whether electrical or mechanical, controls the flow of oil into the motor. I don't quite understand the particular matching of a motor with a cylinder (which you called a jack) in this instance.

how a hydraulic motor works

The hydraulic motor is the component of a Hydraulic System that convert hydraulic Energy from the hydraulic system into mechanical rotational Energy by rotating the shaft.

This is a good explanation of the subject.

I hope this is what you are looking for.
